MEASURlNG-FAUCET.

SPECIFICATION forming part of Letters Patent No. 687,395, dated November 26, 1901.

Application filed June 22, 1901. Serial No. 65.629- (No model.)

To aZZ whom it may concern.-

Be it known that 1, JAMES N. DOUGLAS, a citizen of the United States, residing at North Freedom, in the county of Sank and State of Wisconsin, have invented new and useful Improvements in Measuring-Faucets, of which the following is a specification.

My invention relates to improvements in that class of measuring-faucets which comprise vessels and siphon-tubes for discharging the vessels of their contents; and it consists in a certain peculiar construction the novelty, utility, and ad vantages of which will be fully understood from the following description and claims when taken in conjunction with the accompanying drawings, in which-- Figure 1 is a vertical sectional view illustrating my improved faucet as connected to a tank. Fig. 2 is a detail elevation taken at right angles to Fig. 1 and illustrating the upper portion of my improved faucet. Fig. 3 is an enlarged detail section illustrating the Vent-tube and the valve therein; and Fig. 4: is a plan view, partly in section, illustrating a modified faucet embodying two vessels.

Referring by letter to the said drawings and more particularly to Figs. 1 to 3 thereof, A is a barrel or other suitable tank or receptacle designed to contain liquid to be measured.

Bis the vessel of my improved faucet, and O is a tube connecting the tank A and vessel B and provided with a cock D, which in one position is adapted to establish communication between the tank and vessel and in its other position 'to close such communication.

The vessel B may be of any suitable material and construction, although I prefer to form it of glass and provide it with a metallic screw-cap a, connected to the tube 0, as shown.

D is a vent-tube which extends through the cap or top of vessel B, and E is a siphontube the inner arm of which extends downwardly through said cap or top to a point adjacent to the bottom of the vessel. The venttube is provided within the vessel B with one or more apertures b, and is also provided below and above said aperture or apertures with seats 0 d for a globular valve F, the stem e of which is connected to a float G disposed below the vent-tube, as shown.

In practice the valve F normally rests in the position illustrated, and consequently when 'cock D is turned to establish communication between the tank A and vessel B liquid will flow from the former inlo the latter until the float G is raised by the liquid and the valve F is thereby carried against its upper seat (I, when the escape of air from the vessel being checked the siphon-tube will discharge the contents of the vessel. As soon as the flow of liquid through the siphon-tube commences the cock D is closed, so as to prevent the resumption of the flow of liquid into the vessel B when the valve F gravitates to its lower seat a, incident to the discharge of liq uid-from said vessel 13.

As will be readily appreciated the outer arm of the siphon-tube is adapted to serve the purpose of a funnel when it is desired to discharge the measured liquid into a bottle or the like.

In Fig. 4 of the drawings I have illustrated a modified construction in which two vessels B, equipped with appurtenances similar to the vessel B, are employed. These vessels B are connected to two arms f of a three-way casing O, the other arm g of which is connected to the tank A. In the casing 0' is arranged a cock D which in the position shown in Fig. 4 is adapted to establish communication between the tank and the vessel B to the left and in its opposite position to establish communication between the tank and the vessel B to the right and close communication between the tank and the said vessel to the left. From this it follows that by simply manipulating the cock D at intervals the operator is enabled to effect the filling of one of the vessels B while the other is being discharged of its contents, and thus, if desired, quickly empty the tank.

-It will be appreciated from the foregoing that, while simple, inexpensive, and easily operated, my improved faucet is calculated to accurately measure the liquid that passes therethrough.

By virtue of the siphon-tubes and venttubes being connected to the caps a it will be observed that when the vessels are screwed out of engagement with the caps ready access may be gained to the inner ends of the tubes for the purpose of cleaning the same.

' I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and pre ferred embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood asconfining myself to such specific construction and arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my claims.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The measnringfaucet described comprising the screw-cap, the supply-tube connected thereto and having a cock, a vessel screwed into engagement with the cap and removable therefrom, a siphon-tube having the inner arm connected to the screw-cap and also having the end of said arm arranged in direct communication with the interior of the vessel and adjacent to the bottom thereof, and the end of. its other arm arranged outside the vessel, the vent-tube connected to and depending from the screw-cap and having an aperture or apertures at an intermediate point of its length and concave valveseats disposed above and below said aperture or apertures, the globe-valve interposed be and removable therefrom, siphon-tubes having their inner arms connected to the screwcaps and also l1aving-the ends of said arms arranged in direct communication with the interior of the vessels and adjacent to the bottoms thereof, the vent-tubes connected to and depending from the screw-caps and having apertures, and concave valve-seats disposed above and below said apertures, globevalves interposed between said valve-seats and having stems depending below the venttubes, and floats connected to said val vestems.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
